An example is J S 7 2 0 2 8 26 ways to choose any letter to go where the J is, times 25 ways to choose any DIFFERENT letter to go where the S is than the one chosen to go where the J is, times 10 ways to choose any digit to go where the 7 is, times 10 ways to choose any digit to go where the first 2 is, times 10 ways to choose any digit to go where the 0 is, times 10 ways to choose any digit to go where the second 2 is, times 10 ways to choose any digit to go where the 8 is. That's 26x25x10x10x10x10x10 = 65000000 Sixty-five million. Edwin
